Blood Splatters in New Red-Band Trailer for 'Deadpool'

This movie is still a big question mark, since it's so obviously a complete tonal shift from most superhero movies. What's weird is that it's actually still wanting to be a part of the X-Men universe in spite of it- it looks exactly like the comic on which it's based, but will that brutally violent/simultaneously humorous tone work for audiences used to so many innocuous fast food comic book movies? I do give the movie all the credit in the world for at least trying something different, but that didn't exactly work out so well for Kick Ass, if I recall. It may have some devoted cult fans though.
